I just flashed 4.0.1 and unrooted my Gnex.

Now on 4.0.2 from the OTA, I still have the problem.

The battery icon is always charging .

It look like a hardware problem to me.
[Samsung Galaxy Nexus] freakmax:
I cleaned the battery contact with the contact cleaner.

My phone is working perfectly for now.
[Samsung Galaxy Nexus] owl777:
after fully discharging and charging it again the problem is bask... i hate this device already.
[Samsung Galaxy Nexus] times_infinity:
You need to get a replacement. I had the same issue with one of my LTE Nexus replacements. I have two batteries and no matter how much I switched between them the problem persisted. Only way I know to remedy this is to get a replacement
[Samsung Galaxy Nexus] dtokez:
Its certainly a hardware issue. I tried a factory reset and no good for the person that has asked.

Mine has gone for repair, flakey design i think!
[Samsung Galaxy Nexus] leyvatron:
For those that send it in: How many days without your phone?
[Samsung Galaxy Nexus] vonapets:
I'm without mine for upto 10 working days. So far its been 4!
[Samsung Galaxy Nexus] dtokez:
A week for mine so I'm told
[Samsung Galaxy Nexus] Cptrucker:
problems dissapeared.. for now

Hey guys.

I also have this problem with my GN, tried flashing custom ROM's, tried taking out the battery and re-inserting after 20-30 sec. Tried discharging the battery fully and then leaving it to charge over night but no change.. I have spoken to my retailer and they are willing to take it in, but first i had to make it stock again.. So i did.. Since then, the phone is super.. i'll keep updating if or when the phone acts up again. If so, it's right back to the retailer.

Edit: the phone has started acting up again now... I guess its time to send it back :-(
[Samsung Galaxy Nexus] leyvatron:
My phone has not acted up since. I didn't do anything different but I haven't got it for a few days.
[Samsung Galaxy Nexus] RaQHoliday:
I currently can't charge my phone while turned on. It either won't register that it's charging or will turn off completely when the (OEM) charger is connected. It seems to charge when turned off, although I get no indicator on-screen showing that it's charging.

I went ahead and ordered this part last night, since it was only $10; any way you could do a detailed walk-through of how to replace it? I understand that it's not that hard, but after paying $620 for a device, I'm pretty wary of disassembling it without knowing exactly what I'm getting into.
[Samsung Galaxy Nexus] leyvatron:
I would just get an external battery and charger or let Sammy do the repair. I know I could do it but wouldn't want to risk my hundreds spent on this phone.

Remove the battery and leave the USB plugged in... repeat over. That's what I kept doing....not a true fix but worth a try.
[Samsung Galaxy Nexus] KingCong:
I've the same problem with mine. Brought it back to Vodafone store (Ireland) and they sent it to "be examined by their engineer". Will be up to 10 working days before I hear back from them, in the mean time they've given me a crappy on dumb Nokia as a loaner. Phone warrantees suck!
[Samsung Galaxy Nexus] dtokez:
well I got a call to say mine was back, went down there and they said they couldn't repair it in time so gave me a new one....which does not charge at all!

not happy, yet another trip to town :(
[Samsung Galaxy Nexus] RaQHoliday:
Ok, further problems. I can now charge the phone while turned on but only from the wall. If it's turned on and I connect it to a PC or car charger, it shuts down immediately and has to be unplugged in order to turn it on again. It will also charge (from the wall) with the phone off, but I get no on screen indication of it charging... no white battery charging indicator, no battery with lightning bolt, nothing.

Also, if the screen turns off for more than about 5 seconds, the phone shuts down and I have to power it back on. To ameliorate this I've got it set to remain awake while charging, and I leave it plugged into the wall virtually all day while at work, but I'm not happy about being tethered to a wall socket on a MOBILE PHONE, obviously. Hopefully this part arrives by Monday.

I called Samsung support yesterday to discuss my options, and they of course didn't have my IMEI in the system. I was told based on my phone model that it may well be covered if the phone isn't rooted, but because it shuts down the second I connect it to a PC, it's going to be nigh-impossible to return it to stock form, so I'm probably looking at at least SOME cost to have it repaired.

This whole "replace the part yourself" thing is looking better and better all the time.

*studys Youtube Galaxy Nexus disassembly videos*

***Update - I tried rebooting into the Bootloader menu; the screen flashed the menu for a split second, then the phone shut down. I think it literally shuts down the second it attempts to recognize a possible USB (not just charge) connection, in which case I'm really hoping changing the port will rectify it.
[Samsung Galaxy Nexus] dtokez:
well they had to give me a brand new one, but I'm expecting the fault to occur again at some point :(
[Samsung Galaxy Nexus] adsal634:
I did the same since my GN finally gave out and wont charge AT ALL anymore!

A detailed video would be great. Id be more than ok with donating for your help and time.

Please help us out!

Thanks
[Samsung Galaxy Nexus] Melhouse:
Watch this: http://www.youtube.com/watch?v=6sD6LRfJHSk

Follow the instruction until 3:17, instead of taking of the whole board, you can just flip it over. This way you don't have to undo the volume buttons, and the coaxial cable beside it.

Be also aware that the motor at 3:00 can be quite hard to pry off as it is fastened with adhesive tape.

The board itself is also fastened with adhesive tape.

Good luck ;)
[Samsung Galaxy Nexus] RaQHoliday:
Well good news and bad news.

Good news: Part came today; watched the disassembly video a few times, got up the courage and went for it. Went off without a hitch, was actually not too difficult at all.

Bad news: Did not. Change. A THING.

Can still only charge the phone from a wall charger, not from a computer. Any time I attempt to charge it from a comp or connect it to a comp it IMMEDIATELY shuts off; also, if I let the screen time out and shut off, the phone shuts down within 3-5 seconds (as long as the phone isn't actively doing anything; if I'm listening to music or something, it will stay on, but it turns completely off when it "idles" so to speak).

No idea what the problem is now. :confused::(
[Samsung Galaxy Nexus] halo0:
Which case opening tool did you use?

---------- Post added at 10:26 PM ---------- Previous post was at 10:25 PM ----------

:( When did your problem start? For me it was when I started using the OEM extended battery (2000mAh).
[Samsung Galaxy Nexus] RaQHoliday:
Oddly, I bought a Philips Android dock two Saturdays ago... everything worked fine and then the following Tuesday **** started acting funny.

The Android dock required the Fidelio app to be downloaded (along with Songbird), which automatically turned on Bluetooth to stream music to the dock speakers... not only can I not connect to a comp, but I can't connect to the dock without the phone turning off either. I obviously considered that first and uninstalled both Fidelio and Songbird to see if that corrected the issue, but it hasn't. I've started uninstalling non-stock apps at this point to see if anything changes, but no luck thus far.

I still don't understand why the phone shuts down almost immediately when I boot it into the bootloader menu either... it literally flashes the screen with the Android for half a second then immediately turns off, just like if I plugged it into a computer. I can turn it back on seconds after with no problem, but I'm at a loss for an explanation.
[Samsung Galaxy Nexus] Melhouse:
A knife :)
[Samsung Galaxy Nexus] isinisterx:
Is this normal battery life? I was just playing some games and the battery was dieing like crazy
[Samsung Galaxy Nexus] Sharp12:
Mine charges fine when the phone is on.

However, if I turn the phone off while the cable is plugged in, I get the white battery icon. It'll stay there until I pull the battery. Today for whatever reason, my phone restarted when I was sleeping, leaving this icon on while I missed my alarm and slept through the day.

I think it's time I begin my repair process as well.
[Samsung Galaxy Nexus] Sharp12:
Oh man, that picture cracks me up. That negative slope is pretty large towards the end.
[Samsung Galaxy Nexus] halo0:
Knock on wood, my battery has gone back to normal.
[Samsung Galaxy Nexus] danielvc:
I got the same weird battery-charging-idicator when it actually isn't charging. Phone went nuts. Tried everything: relocking, flashing stock, wipe battery-stats etc, but this helped. Getting normal battery-thingy for almost two days now, that's just great. Thanks!
[Samsung Galaxy Nexus] leyvatron:
I also had the same issue and it went away. I pulled the battery a few times while it was charging and left it plugged in for a while, I also drained it a couple times until the battery was dead. I had this problem for 2 weeks and it completely went away now.
[Samsung Galaxy Nexus] chuckdz3:
Sounds like a lot of people are trying different 'tricks' to get around this issue but it always seems to come back? I also have the issue of not charging sometimes and sometimes it works. So I know I need something to be replaced internally. I would feel much more comfortable having Verizon or Samsung fix it or replace the phone but as of right now I have unlocked the bootloader and rooted it there for 'voiding' my warranty. My PC will NOT recognize my device when I plug it in so I can't flash stock images, unroot and relock the bootloader.

Anyone else with this issue or is everyone stock with a locked bootloader?
[Samsung Galaxy Nexus] danielvc:
This topic is originally about the nexus thinking it is charging when it isn't. So you are commenting (with some others) in the wrong topic.
[Samsung Galaxy Nexus] lukasb9000:
I got the same problem!!! Glad I'm not alone =D

So it seems to be a defective usb port ?!
[Samsung Galaxy Nexus] Roxxer_x46:
i solved this issue(almost for me :P)

there are the steps:

1 eject the battery

2 plug the charger

3 insert the battery

4 wait until the phone recognizes the level of battery (first appears a icon with the baterry and a ray, and next the icon with the battery level)

5 unplug your charger

6 turn on the phone.

7 should be normal now... if not... well it worked for me...

I think that internally it has another internal battery that keeps the clock running, and keeps the battery meter alive. If this metter screws with hard customizations (like when you install a custom rom, or kernel), you just need to restart it while android is not running... it happened to me after flash franco´s custom kernel... firstly the battery was almost charged, after i had installed the kernel the battery was at 15%, next i saw the issue, after install other rom, the same happen, another kernel... the same... i thought that it were a hardware issue(like the volume issue). but it never happen before when i was in the stock android 4.0.2 so... its not a hardware issue(i thought, maybe its a bootloader issue who knows :rolleyes:), well this solved this issue.. now its back to normal(include custom roms)
[Samsung Galaxy Nexus] Melhouse:
Please don't jump to conclutions. You may be exited that you don't have the sympthoms after doing all this "magic", but please wait some time before claiming it fixed. If you read this entire thread you see that many have tried this stuff, but only as a temporary fix. The only real solution to this is to change the USB charging board, this is certain a hardware issue.

All that "internal battery" that "keeps the battery meter alive" is all in your thinking and no root in reality..

Please give it a few days/weeks and see for yourself. Also be sure to state what issues you are experiencing when you propose "solutions".
[Samsung Galaxy Nexus] alghtani33:
I jest received my phone from Samsung service, they changed the USB charging port. and they put a yakjuxw built, and the phone was working great.

After that, I have changed the built to yakju and the problem started again.:mad:
[Samsung Galaxy Nexus] brandonb81:
I just started having this problem yesterday. :(

I'm on the leaked 4.04 rooted... It's been fine since I bought it which was about a week after release. I'm on the Verizon CDMA LTE version.

I purchased the $7 a month insurance from Verizon so I'm going to go down to the Verizon store today and see if I can get a replacement. I'm in the process of backing everything up with Titanium, then back to stock to bring to Verizon.

What a pain in the ass. :mad:
[Samsung Galaxy Nexus] BroodjeBami:
I also started having this problem and it's really annoying. I have ALL the problems mentioned above. Yesterday I couldn't charge, 3 days ago my screen kept turning on and other days other issues happened, all regarding the usb charging port/charging my Galaxy Nexus. Is there really no way to bring this issue in the media? Cause in my opinion this is a BIG issue.

Edit:

I think there's a chance that the problem could be software. Anyone having this problem running something higher than Android 4.0.2 (which I'm running)? If nobody is, then the problem could be well solved in Android 4.0.3 or higher and that will also explain why Google doesn't really find this issue a big priority.
[Samsung Galaxy Nexus] d.brown:
I'm on 4.0.3 an having to charge my battery with an external charger plus usb not working... Happy to use file expert and dropbox plus titanium to sync my backup to the clouds!

I'm sure it's a software issue, the phone is shutting down the usb port, maybe it's reading the wrong values, and as a failsafe mechanism...?
[Samsung Galaxy Nexus] BroodjeBami:
Hmm... Really sucks. So anyone with 4.0.4 with this problem? (I thought 4.0.4 has been out already, right?)
[Samsung Galaxy Nexus] prankmonkey:
any news on possible causes and fixes to this?

its started happening to me recently. causing quick battery drain when i get to about 15% due to screen wakes :(

problem is intermittent for me

charging is fine atm
[Samsung Galaxy Nexus] cugel:
In my experience is a hardware problem. I've had the problem two month ago (4.0.1 Stock) and one week ago (4.0.3 AOKP) and, both times i solved the issue with the method described previously (basically applying soft pressure to raise the internal metal piece inside the microUSB connector). Please be careful as you could damage the connector or invalidate the product warranty

I think that the cause of the problem was a bad quality USB cable or disconnecting the cable with a quick movement, obviously the root cause is a low quality USB connector in GNexus.
[Samsung Galaxy Nexus] adeklipse:
Got this problem, too.

I want to exchange it, but can't transfer my app and data backups to my computer because it won't detect the phone.

Can't sync to cloud, either, because crappy operator costs.
[Samsung Galaxy Nexus] loveact:
yeah, our crappy operator..

damn, my GN is from hongkong and it won't be covered by the warranty..

i hope i won't have the same problem :(
[Samsung Galaxy Nexus] Tweezydak1d:
I had the problem to and it pissed me off to where I bought a replacement USB port but then I used a toothpick to push the charging port up but not putting a lot of force on it but once I got the piece strait my phone has been fine haven't had the problem in over a month. But I also have the replacement part just in case.
[Samsung Galaxy Nexus] adeklipse:
Okay. It seems solved for me.

Flashed a new kernel (this one). Previously with franco M1 and GLaDOS 1.21 and 1.23 all of which didn't resolve my issue.

Which is weird, since I was on franco M1 when the issue started.

I have no idea whether this is hardware- or software-related.
[Samsung Galaxy Nexus] xJeganx:
I was on franco #96 when I got this issue and updating to the latest #98 fixed everything for me. Although it didn't happen immediately when I flashed #96 so it could still be a lingering hardware issue.
[Samsung Galaxy Nexus] palmcrash:
Verizon Galaxy Nexus 4.0.4.

Since around the past week, I'd been also having the same charge/not-charging status issue regardless of whether data/power USB cable's connected, causing the screen to keep turning on & draining the battery.

Battery pull didn't fix it, but after clearing the Dalvik cache via ROM Manager, it's been fine for the past ~5 hours. Crossing my fingers...

[edit]

After 6 hours, the issue's back...

[re-edit]

Seemed to have been just a one-blip issue (split-second) right after I unplugged the cable. It's been fine for a day since the Dalvik cache clean. Crossing all 10 fingers...

[#$@% it]

It's back. Wiping Dalvik Cache doesn't solve it now.
[Samsung Galaxy Nexus] danielvc:
Check above and see if that helps!
[Samsung Galaxy Nexus] chanchan305:
same here

tried everything, problem went away for 3 days and now is back, phone charges ok, but phone keeps turning on and off
[Samsung Galaxy Nexus] billyskip:
I just left the Verizon Store. After a phone call the tech support, it was determined that it was a hardware issue. The Phone displays (charging) when not plugged in, and phone will not charge. Customer service is mailing me a new phone, should arrive in 4 days, and I am to return my current handset.

The verizon store is no longer selling the GNex anymore. I asked why and was told there were problems with the phones.

(SOLUTION) If you are having this issue, I suggest you head to your local VZW store and get a new one. I do not see a "patch" fix for this issue.. Its hardware.
[Samsung Galaxy Nexus] JSY00:
NOT a software problem

Guys, I had this happen to my phone within a week of owning it (a week after release). I almost returned it, but fixed the issue myself. the issue is with the charging terminals touching in the USB/Charging port. Get a flashlight and shine it directly into the port. You'll see the outer part of port is metal, and in the center is a 'tongue' that is also metal, these are the 'terminals'. In my case the tongue was very slightly touching the outer terminal - probably due to the times i carelessly shoved the charger into the port (sometimes upside down). This essentially bent the tongue downwards, and when the two terminals are in contact, the charging circuit is short circuited. I fixed this by taking a pin (though anything flat/thin could work) and pressed the tongue in the opposite direction. This centered the tongue, and by being careful when plugging in my charger, it's never happened since.
[Samsung Galaxy Nexus] kampf:
This started happening to me last weekend. I figured it may have something to do with being in Japan, on 50Hz power or something mundane, but having returned to 60Hz land the problem remains.

I had used my wife's Samsung Nexus S charger for one night instead of my GN unit, and that may have tweaked the center tongue of the USB port downwards. I've used a pushpin to pry up slightly on the connector with hopes that it's so simple.

Note, this is on a completely unmodified GSM Galaxy Nexus running 4.0.4 IMM76D with the 2000MAh Samsung battery.
[Samsung Galaxy Nexus] lilfleck:
What's weird to me is the fact that my phone works fine on two car chargers I have... it works fine on one USB cable I have. It does NOT work on two other USB cables that I use (wall). I was wondering if it was voltage related. It could be connection related... but the "tongue" doesn't appear to be bent towards the other side of the connectors. I will try to bend it slightly to see if I can center it perfectly.

EDIT: after reading more posts from people -- I am leaning towards a hardware issue. I think this is due to the connection the charger makes with the connector. I think it is cheap materials. I didn't have this issue with my Droid X. The car chargers I mentioned above have a super snug fit. Then again, so does one of my USB chargers. I will take a look at the connectors, bend them to normal, and clean with alcohol to see if that remedies it. If not, I will be heading to VZ for a refurb.
[Samsung Galaxy Nexus] MistaBishi:
My Nexus always thinks its plugged into the charger, and flickers between causing it to have the screen on all day and kill the battery. I have tried all the suggestions in here, so I think it's time to return it. Cheers for making quality phones Samsung.
[Samsung Galaxy Nexus] mattarth:
This is the solution that worked for me

The above post from JSY00 worked for me straight away. I couldn't see the tongue touching the outer part, but despite that I still tried the fix. I pushed a toothpick into the port slightly in to lift the tongue away from its closest wall. I also cleaned out a bit of fluff from the port, but I don't think that will have helped much.

My phone now works as it used to, and doesn't say it's charging constantly :). Thank you JSY00! (I signed up here only to report that your method worked).

This solution was free (apart from 1 toothpick required) and saved me a week or two to wait for a repair, which many people have reported didn't make things better. A hardware problem often requires a hardware solution.
[Samsung Galaxy Nexus] xternal:
I have also had success just slightly bending the connection back. However I was still a little bit flaky, so I used compressed air to clean the port and then a little bit of electrical contact cleaner.

Been working like a charm since.
[Samsung Galaxy Nexus] mattarth:
Cleaning

Oh yeah, that was the other thing I forgot I'd done: I blew strongly (closely) into the port. Try not to spit too much and let it dry off.
[Samsung Galaxy Nexus] kampf:
After using a pushpin to tweak the tongue up, I had two days of successful charging before I was unable to get it to work again.

Jamming the pin in again and leaving it for several minutes got me a successful connection and I am now charging again.

I fear that the only way to avoid this issue long-term may be to get the (expensive) Samsung pogo-pin desktop dock or send it in for a replacement USB port.

Annoying.
[Samsung Galaxy Nexus] MistaBishi:
Will be replacing my charging board in the coming weeks, hopefully fixes my issue.
[Samsung Galaxy Nexus] chrysamere:
this fixed my problem

+1, this fixed my issue.
[Samsung Galaxy Nexus] hcarrega:
i have this problem since i have 4.0.4
[Samsung Galaxy Nexus] NerdDevout:
Phantom charging

The OP talks about flickering charging indicator. My phone charges perfectly in wall and car. BUT I have phantom charging indicator and it is killing my battery super fast. I have read every post but I feel like this thread was hijacked by the non-charging issues. Has anyone whose phone CAN charge been able to fix the phantom charging indicator?
[Samsung Galaxy Nexus] voodooboy3000:
I am having the exact same issue for the last two days. Phantom charging icon and the phone constantly waking. I thought it was aokp so wiped everything and started fresh.

OK I have fixed it and was so simple. I had a tiny bit off fluff stuck right at the back of the USB socket . I removed it and the issue stopped immediately
[Samsung Galaxy Nexus] JanxSpirit:
You sir, are a legend. Thank you so much.
[Samsung Galaxy Nexus] killer8297:
Wow you just save me a whole lot of time. I've been using the OTG cable a lot so that might have been what caused the problem.
[Samsung Galaxy Nexus] sensorama:
Solved it for me aswell. I actually sent my device to a servicecenter and they claimed it was waterdamaged.
[Samsung Galaxy Nexus] kampf:
This is definitely an issue with the center connector.

I have used, as mentioned in a previous post, a pushpin to encourage the tongue to bend back up slightly. I've also used the rounded end of a paperclip and left it in there for 30 minutes or so before trying to plug it in.

So far, so good.
[Samsung Galaxy Nexus] horm:
I had the issue with the battery charging icon present without beeing plugged in. also if the charging icon was not present the "OS Monitor" app showed about every second an usb connected/disconnected event.

what solved this problem for me: just cleaning the port with some folded paper, was quite dusty in there ;)
